Abstract
The present invention discloses the formulation of an adhesive and a preparation technology thereof. The formulation of the present invention is composed of chloroprene rubber sheets, natural rubber, 210 resin, rosin, coumarone resin, methylbenzene and gasoline No. 120, and the present invention has the technology that the materials are orderly poured into a reaction tank to run for 16 to 18 hours so that qualified products can be prepared. The adhesive is suitable for the adhesion of the materials of leather, rubber, wood, etc., and has the characteristics of strong adhesive force, high tensile strength, low cost and simple processing technology.
Description
The present invention relates to a kind of tackiness agent, particularly a kind of prescription and manufacturing process of chloroprene rubber class tackiness agent.
At present, the general prescription of the neoprene type tackiness agent of widespread use is as follows:
(according to " the adhesive applications handbook)
5 parts in 100 parts of zinc oxide of chloroprene rubber
2 parts of 83 parts of α-phenyl of resol-β naphthylamines
15 parts of 4 parts of coumarone indene resins of magnesium oxide
The tackiness agent of the type that has also need add an amount of antioxidant d and promotor etc., comprises calendering process in process of production.This class tackiness agent has the better physical performance.But adopt the cost of tackiness agent of above-mentioned prescription higher, the technology more complicated.
The object of the present invention is to provide a kind of cost low, the prescription and the manufacturing process of the simple tackiness agent of the good technology of performance are by the product Joint strength height that the present invention produces, stable performance.
The objective of the invention is to realize with following scheme: the prescription of tackiness agent is by the A90 neoprene sheet, natural rubber, 210 resins, rosin; Ancient marlon resin, toluene, No. 120 gasoline is formed, and above-mentioned materials is dropped into retort according to a certain ratio successively in proper order, turns round and can produce qualified tackiness agent in 16～18 hours.
210 resins are rosin modified phenolic resins, and in the presence of alkaline contact substance, through polycondensation, the initial stage polycondensate of making reacts under heating state with rosin and makes by xylenol and formaldehyde, and this product is by Shenyang City's two estrade resinifying plant produced.
Do not add MgO among the present invention, ZnO has reduced calendering process, thereby minimizing equipment.Someone proposes neoprene latex and adds MgO, and ZnO is after the rubber mixing machine high-temperature mixing, and molecular chain will be subjected to destruction to a certain degree, thereby will influence the bonding strength of tackiness agent.Owing to add natural rubber among the present invention, play suitable effect for the pulling force that increases tackiness agent.Because prescription of the present invention adopts natural rubber and does not add MgO, ZnO, anti-aging agent, lek is received etc., has directly reduced cost, and technology is also very simple.
Concrete prescription of the present invention and technology are provided by following examples.
The present invention's prescription is (weight percent):
(1) the A90 neoprene sheet 13.27%
(2) natural rubber 1.47%
(3) 210 resins 5.16%
(4) rosin 0.29%
(5) ancient marlon resin 0.147%
(6) toluene 64.923%
(7) No. 120 gasoline 14.74%
Above-mentioned materials is dropped into retort in the following order successively:
Promptly (1) drops into toluene, and (2) drop into No. 120 gasoline, and (3) drop into the A90 neoprene sheet, and (4) drop into natural rubber, and (5) drop into 210 resins, and (6) drop into ancient marlon resin, and (7) drop into rosin.
Successively each material is dropped into retort in the following order, the retort entry into service was turned round 16～18 hours simultaneously, promptly finished reaction, produced tackiness agent.
The adhesive of being produced by the present invention is suitable for the bonding of the materials such as leather, rubber, timber, and it is strong to have a bonding force, the tensile strength height, and cost is low, and the simple characteristics of processing technology are used and test result shows that physical properties is good through the user.
Claims (2)
1, a kind of prescription of chloroprene rubber class tackiness agent is characterized in that: adopt natural rubber, its prescription is (weight percent):
A90 neoprene sheet 13.27%
Natural rubber 1.47%
210 resins 5.16%
Rosin 0.29%
Ancient marlon resin 0.147%
Toluene 64.923%
No. 120 gasoline 14.71%
2, the manufacturing process of tackiness agent according to claim 1, it is characterized in that: above-mentioned materials is dropped into retort in the following order successively, (1) drop into toluene, (2) drop into No. 120 gasoline, and (3) drop into the A90 neoprene sheet, (4) drop into natural rubber, (5) drop into 210 resins, (6) drop into ancient marlon resin, and (7) drop into rosin, under agitation add above-mentioned materials, finish through 16-18 hour afterreaction.
